Is Intelligence a naturally occurring function of Information Technology?
Maybe, but it depends to a very large degree on the choice of definition.

One of the biggest challenges for AI researchers, neuroscientists, philosophers, and psychologists, has been that the layperson's understanding of intelligence does not appear to correspond to a well-defined concept. This point was most famously exploited by John R. Searle in his paper Minds Brains and Programs.

Consider your definition again carefully, and notice that decision is unbound. Does a rock rolling down a hill make a decision when it 'decides' to roll to the left? If not, Searle and his ilk would argue that a computer isn't making a decision when it decides to execute the next instruction. It is simply obeying deterministic laws of physics.

To escape this problem and still claim that machines are intelligent, you can either chose to believe that rocks make decisions (a view called panpsychism), or that we should behave as though rocks make decisions because doing so gives us a lot of explanatory power (the intentional stance), or claim that humans are no different from the rock or the computer (eliminative materialism). The last option leaves you with the problem of explaining subjective experiences though.

An excellent book that covers the mainstream arguments in this vein is Haugeland's Mind Design II. All the arguments I've outlined here are covered in great detail within. Among modern AI researchers, I'd say there is a split between those who embrace something like the intentional stance and those who embrace eliminative materialism.
